  • How to use 2 or more internet connections on the same network?

    - by Rogue
    Living in a joint family we have 3 internet connections, each floor has one internet connection which is split per floor. Each internet connection is shared between 4-5 computers using a switch per floor. Each of these internet sharing networks are independent of each other. What I want to achieve here is a local network (for local messenger and file sharing) that can combine all the 3 independent networks, problem is that whenever I try to do that the whole network tends to use just one internet connection. I have all the necessary hardware. How do I solve this problem, one approach could be that I could get one PC to act as a server and bridge the internet connections and then the whole network would have to access the internet through this server. Theoretically this could be possible but I have never tried this approach in real life. Also if certain computers need be restricted from internet access how would this be possible on the same network?

  • Having to Toggle Between Two Sets of Video Drivers

    - by Maarx
    So, I've got a Win7 64-bit gaming PC with GTX 260's. Recently, StarCraft 2 had an issue with flickering, which NVidia fixed with a new set of drivers. However, these new drivers induce unplayable graphical errors with Neverwinter Nights 2, something me and my friends still play from time to time. I am seeking advice on the "best" way to rectify this situation, to be able to switch between two driver releases, without compromising the stability of my system (if Windows stability isn't an oxymoron). I'm wondering if Windows 7 is structured in such a way that I can constantly reinstall these two sets of drivers back and forth overtop each other, possibly six or eight times a day, without very quickly driving myself to reformat to maintain that "just like new" performance. I'm loathe to have to reformat the drive and maintain two copies of the operating system, but I'll do it if I have to.

  • Apple TV photo fail

    - by Tony
    I just bought the new (2nd gen) Apple TV. Everything works beautifully, except for Photos. I have 25,000 pictures on my computer, which creates 3 issues with Apple TV 1) It takes roughly an HOUR to load my photos, every time! (if I navigate anywhere else, its has to reload all over again next time) 2) It condenses all of my folders-sub-folders-sub-sub-folders into just the top folder. Having only 5 top folders with 5,000 pictures each is pretty much useless. 3) It has an artificial cap of 20,000 pictures, after which it won’t load more. The first two are the big ones, since they pretty much make the product unusable. I have called apple support (they just said “sorry…too bad”), and have checked all the online forums I can. Also it is definitely not a connection issue, as it streams HD Netflix movies with ease. Does anyone else here have this issue, and/or hopefully some solutions?

  • There is a porn domain pointing to my site

    - by Nicolas Martel
    Let's say example.com is my real site, and fooexample.com is the porn site. fooexample.com are pointing to my ip. Now you could think, just don't mind it right. Well the thing is that they are driving load of traffic. Not only that, but my main domain example.com become unavailable after a couple of minutes and the only domain that work is either fooexample.com or none of those 2. What i have done so far was using mod_rewrite to redirect the porn site to google but my domain still become unavailable. Blocking the ips served no result either. I hope someone will be able to help me because this is a huge problem right now. Thanks.

  • Should I use UPS with my laptop to extend the battery life?

    - by Mehper C. Palavuzlar
    I recently bought a new Vaio laptop which has a 4400 mAh battery. I will use it at home most of the time, and I have an unused uninterruptible power supply (UPS). Should I remove the battery and connect my laptop to UPS? If I do that, how much does it effect the battery's life? I know that batteries stand longer when kept in half-charged in a cool place, but their lifespan decreases in time due to age effect as well. So is it worth to keep the battery out of my laptop, use a UPS instead and mount it when necessary? or should I continue to work with battery mounted?

  • What you'd need to setup BBS?

    - by raspi
    What I need to setup BBS nowadays? I'm thinking of BBBS or PCBoard (no telnet! too new technology). What I've thinked so far, I'd need: virtual machine which runs DOS and hook that virtual COM-port to somekind of virtual VoIP modem software somehow (is there any?). How you can call to it across internet? Can you use HyperTerminal straight with that virtual/real modem? Or will VoIP just garble the modem data and nothing will work?

  • On Windows 7, how do I fix my cmd.exe icon and remove cruft from the jumplist

    - by sb3700
    Hi. When installing drivers for my Gigabyte motherboard, I installed a "Games" link which ran from a batch file. This was pinned to the taskbar by default. As a result, it changed the icon for cmd.exe to the icon for Games. I uninstalled the Games and it got rid of the icon leaving it with a white rectangle thing (I can post screenshots on request). There is also a link on the jumplist to open Games, which just opens a cmd window. I've tried rebuilding my icon cache as per Changing Windows 7 pinned taskbar icons, but this only removed the white rectangle icon, leaving me with no real icon. c:\windows\system32\cmd.exe still has the appropriate icon in explorer, just not on the taskbar. Any ideas on how to fix this annoyance?

  • Trick to enabling FTP upload from an app in Windows 8?

    - by Craig
    I have an older Win32 app that uses FTP to upload some data to a server from time to time. This app works great in Windows XP and has been working fine in Windows 7 and Vista. For some reason, when running under Windows 8 it has trouble uploading its data. It appears to connect and upload the data OK but it has times out when disconnecting. The data does not appear on the server. I have limited visibility into the app while it's running so sorry for the vague nature of the description. My question is: Is there some security setting in Windows 8 that would keep this app from using FTP? When I check the settings it looks to me like I have it set up to prompt me about any permissions problems it might have, and I'm not seeing any prompts. I've tried running this app in XP/SP3 compatibility mode with no luck. At this point I'm just looking for some clues as to where to look.

  • Software that will burn DVDs with a SFV or Pararchive file for each disc?

    - by Matt
    I'd like to burn several thousand RAW files (.DNG) of around 10-30 MB each to DVD to backup my photo archive. I'm looking for software that can do this and include an SFV-type file on each disc burnt. These are my requirements: compression is optional, and probably not desirable due to the extra time involved files should be spread amongst the discs as self-contained units, i.e. I don't want to have to load files from more than one disc to be able to read the files on that disc, so that excludes WinRAR's spanning options I don't want to spend time writing ISO images first as this will be a task I'll need to repeat often as I add new images to my archive - the software should write to the DVDs for me as simply as possible I'd like the SFV/Pararchive/recovery record to be stored with the files on each disc, so it only references the files on that particular disk Thanks in advance!

  • System failure - need diagnostic recommendation

    - by Ladislav Mrnka
    I have big problem with my computer. Configuration is: Intel i7 + 6x2GB OCZ DDR3 Motheboard: Asus P6T Deluxe V2, HDD controller configured to AHCI Main drive: OCZ Vertex 2 (SSD) - contains all installed programs and system Second drive: Samsung SpinPoint - contains User profiles, ProgramData, virtual machines and databases Third drive: Samsung SpinPoint - data drive + backups OS: Windows 7 Ultimate x64 I have never had any problem with this computer until now. During weekend my computer completely crashed without any reason. Each time I tried to boot to Windows I got BSOD with message BAD_SYSTEM_CONFIG_INFO and automatic restart (I didn't install any new SW or HW). But after restart main OCZ drive was disconnected (not detected by BIOS). When I turned off and on computer, the drive was again connected. It also happend every single time I tried to repair installation somehow. It ended with some error and after restart drive was disconnected. The only thing which worked was format + fresh install. After installing almost everything I wanted to install Visual Studio 2010 Ultimate (complete installation without SQL Server Express). During installation of VS itself I always get BSOD - it is too fast so I'm not able to read description. After restart it searches for all disk drives for really long time and sometimes it changes boot drive so the system is not able to start - Bootmgr not found. After reconfiguring BIOS the system starts. There is no event describing the failure in Event viewer. Installing VS 2010 is absolutely necessary for me. I need help with diagnostic. I need to find where is the problem - I expect that the problem is in OCZ drive or in HDD controller on motherboard but I don't know how to find it. All components still have valid warranty. Can you recommend me some approach or tools to find the problem? Edit: I'm still looking for source of the problem. New information is that Windows are not able to perform check disk (Chkdsk) on the SSD system drive. After restarting it always starts checking drive and in part where files are checked it fails with BSOD - BAD_SYSTEM_CONFIG_INFO. After next restart and skipping check disk tests the system runs.

  • What port should I use for my reverse proxy to Apache 2 from nginx?

    - by meder
    I have nginx setup as the defacto port 80. I want to setup django+mod_wsgi on Apache2. I'm worried if I leave Apache2 as 80 it will cause a conflict. Is it better to avoid the headache and change Apache to a different port? server { listen 80; server_name work.domain.org; access_log /www/work.domain.org/log/access.log; error_log /www/work.domain.org/log/error.log; location / { proxy_pass http://127.0.0.1:8080/; proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Magic-Header "secret"; client_max_body_size 10m; } }

  • System will only boot into a Live CD with core disabled in BIOS and ACPI off.

    - by CookieOfFortune
    I have a system that was running a Q6600 and Windows 7 RC. It crashed last night into a BSOD with a MACHINE_CHECK_EXCEPTION. Now it does that every time it boots into Windows. I tried using my Ubuntu Live CD, but the kernel would error out, the stack trace showed something along the linse of "Can not synchronized to one of the CPUs". Working from this, I enabled the "Limit CPU to 3 cores" option in my BIOS and tried again. This time, it seemed to have died after an ACPI call, so I disabled that during the boot and now it is running from the Ubuntu Live CD, showing 2 cores. Does anyone here think I have any hope or is it simply a CPU waiting to die? EDIT: 1 core now.

  • How to configure an ASUS motherboard.

    - by Absolute0
    I have an ASUS P7P55-M motherboard running with an Intel Core i5-750 processor and 4 GB RAM with 1600 MT/s speed. For some reason the default settings of the motherboard make all the components run at half their optimums. I have switched to the "D.O.C.P." profile and supposedly everything is as it's supposed to be (verified with CPU-Z). There is also an "X.M.P." profile and a manual one. Are either of the DOCP or XMP safe to go with? I wouldn't use the manual mode as I would likely mess something up real bad. XMP seems to be more memory oriented.

  • HDFS datanode startup fails when disks are full

    - by mbac
    Our HDFS cluster is only 90% full but some datanodes have some disks that are 100% full. That means when we mass reboot the entire cluster some datanodes completely fail to start with a message like this: 2013-10-26 03:58:27,295 ERROR org.apache.hadoop.hdfs.server.datanode.DataNode: java.io.IOException: Mkdirs failed to create /mnt/local/sda1/hadoop/dfsdata/blocksBeingWritten Only three have to fail this way before we start experiencing real data loss. Currently we workaround it by decreasing the amount of space reserved for the root user but we'll eventually run out. We also run the re-balancer pretty much constantly, but some disks stay stuck at 100% anyway. Changing the dfs.datanode.failed.volumes.tolerated setting is not the solution as the volume has not failed. Any ideas?

  • Weblogic Threads Usage

    - by Hila
    I have an application deployed on WebLogic 10.3, which exhibits a strange behavior. I am running a constant (not too high) load on my application (20 concurrent users, running a light activity). The response time is reasonable (well below 100ms after the application stabilizes) Memory consumption seems fine (My application creates a lot of short-living objects, but they are garbaged collected so the overall memory consumption stays under 500 mb). Threads stats seem healthy as well: And yet, after I leave my test running for a while, more and more execute threads ("[ACTIVE] ExecuteThread: '3' for queue: 'weblogic.kernel.Default (self-tuning)'") are created, until eventually the application crashes: This test hasn't been running for a long time (All the new threads that you don't see in the first screenshot were created while I was writing this question), and I've seen much more threads being created. Any idea why these threads are being created?

  • Snow Leopard Hangs at Login Window

    - by jessecurry
    I've had an issue for the past few months, but I rarely restart so it hasn't caused too much trouble. Basically, when I start up my Mac (iMac10,1 - 3.06GHz Intel Core 2 Duo, OS X 10.6.3) everything proceeds as usual until I reach the login window. The login window displays normally, but keyboard and mouse input seem to be ignored. This condition persists for around 5 minutes at which time everything goes back to normal. While the login window is frozen my second monitor appears entirely blue, the second monitor receives a background as soon as the login window becomes responsive. If I startup while holding SHIFT the problem still occurs, but the freeze is much shorter. Looking through my logs I see no activity during the time that the login window is frozen. I've attempted to repair disk permissions, and gone through every possible maintenance option in Cocktail.

  • Windows 7 cannot burn a DVD-R at 4x or 8x? (it seems to have to use the MAX speed)

    - by Jian Lin
    Windows 7 is great to have the ability to burn an .iso into a DVD-R, but it seems like there is no way to change the speed to 8x or 4x? (so it may go "max", which is 16x) because some of my DVD drives cannot read data all the time if the disc was burned at 16x, that's why usually i limit it to 8x. also, some articles say that disc burned at 4x can last a longer time, so i am tempted to burn something at 4x sometimes. any method or hack that can make it happen?

  • Grub: Legacy 'ask' parameter no longer supported

    - by leeand00
    I'm trying to change the resolution on my base shell (the Ctrl+Alt+1) shell in Debian so that it supports my ViewSonic monitor. The shell appears really fuzzy when it is displayed on my lcd monitor, but GRUB looks fine when it's displayed. In I tried changing part of the GRUB_CMDLINE_LINUX_DEFAULT to 'vga=ask', and now I get the error on booting up 'Legacy 'ask' parameter no longer supported' Has this 'vga=ask' value been changed to something else? Note, I tried setting it to 'vga=782' after finding a list of screen modes here and the shell font got real huge for a few seconds during boot up, and then switched back to it's awful fuzzy self again, when I went to use the Debian Bash shell. UPDATE Tried suggestion in this question, it works without fuzziness until the last resolution change which displays the user login to the shell.

  • Strange sound from Laptop, Microphone, Speakers or Soundcard?

    - by David Schilling
    I have recently purchased a second hand computer. There didn't seem to be anything wrong with it on purchasing, however recently I have noticed a small issue. Any time I play sound or listen through my headphones, I can hear what seems to be the CPU working (ie when beginning a new task, there is a small crackling). Also if I tap my laptop I can hear the sound louder, as if it is being picked up by the mic and then playing that sound in real time through the speakers or headphones. I have tried reading other topics but cannot find an answer to this question. These are the specs I am running on; Windows 7 Home Premium 32bit Pentium Dual Core CPU T4300 @ 2.10Ghz 2.10Ghz I hope someone can help me with this issue, it would be much appreciated.

  • How to Set "<options>" in fstab - Manual Mounting is Successfull

    - by nicorellius
    I am not real familiar with fstab yet, so I have a couple questions. When I use this command to mount devices: sudo mount -t cifs -o username=admin //192.168.1.134/share_name /mnt/share_name With passwords: sudo="local user password" password="password for device" How do I translate that into an fstab entry? So far, I have tried this in the fstab and mounting fails: //192.168.1.134/share_name /mnt/share_name cifs default 0 0 This is where the question comes in. Where I have default, should there be something instead, indicating username=admin, etc?

  • What would be the best way to correlate logs and events on several hosts?

    - by user220746
    I'm trying to build a log correlation system on multiple hosts. SEC seems interesting but I don't know if it will cover my needs. How could I correlate system events, logs, network events, etc. on multiple hosts at the same time, in real time? Examples: If 5 failed logins happened on host A the last minute and if firewall B has denied lots of access on differents ports on A, then we assume there is a potential attack in progress on A. If the Apache service on host A didn't receive any request for the last N minutes and Apache service on host B did, then the load balancing could be faulty.

  • What poor management decisions have you had to deal with?

    - by tombull89
    As a junior technician I've had to deal with (or will have to deal with) some problems in the past and only being a junior technician I don't have the confidence or respect from management staff to speak up. For instance, we're having a entirely new system. From Windows Server 2003/XP going to Windows Server 2008 R2/Windows 7/VMWare/Digital Signage and the current amount of time dedicated to the training of the IT support department currently stands at 0. They seem to think that all IT systems are the same and are going to get a bit of shock when I can't help them. I think there;s some UK legislation saying a school/business have to put money and time aside for training, but I'm not sure. What have you had to deal with?

  • Identify Long Running or Slow PHP Scripts

    - by Kirk
    I have web server that is getting around 25K visits a day up at yougetsignal.com. Sometimes the site feels a bit sluggish. I am hosting it on nginx with php5-fpm. Is there a way for me to see a list of all of the long running requests that are coming to the site? I'd love to have a real-time list of all of the active requests that PHP is handling and how long they have been running. Kind of like top, but just for the web server. This would let me know how long requests are taking and which script is the culprit. Anyone have any ideas on how I can do this?

  • WIth more mobile users, my geo ip database is becoming useless.

    - by Marius
    Hello there, I've been enjoying the benefits of Geo IP lookup from database for some time. Its great. People are increasingly trying to access my site from a mobile phones or 3G modems, and their physical location seems to have little relation to whereabouts my IP lookup tells me they are. A user who is on the east cost of my country, may be looked up as being in the far inland, or up north. And one user may be reported as being in one location in one moment, and seconds later, be 100s of kilometers away. This is becoming a problem, and I need to find a solution. I am already updating my database monthly, but it has little effect. What can be done? Thank you for your time. Kind regardsMarius

  • DDoS attacks to PBX

    - by user316687
    I'm wondering if DDOS attacks to PBX or telecommunications systems is possibe real. According to this links: http://threatpost.com/en_us/blogs/firm-sees-more-ddos-attacks-aimed-telecom-systems-073112 http://news.softpedia.com/news/DDOS-Attacks-Against-Telecom-Systems-Cost-as-Little-as-20-16-Per-Day-284875.shtml it is possible. There are DDOs attacks to web servers, which mostly give them so much concurrent loads or connections that service get unavailable. Many government or non-profit organizations that suffered this kind of attacks, eventually could choose to shutdown their web server and that's it, waiting for these attacks to end. For a DDOs attacks to PBX, I imagine that it would result in telephones getting busy or ringing all the time unstoppably. This kind of attack could really damage any kind organization. Is it possible to do that or are we just in the beginnings?
